How can I start a workspace project for connection with WebIQ API

Hellowebiq-sk

I use the WebIQ API in a standalone html file.

When I start my java script with the API commands, before I loaded my workspace project into the Designer I get an error (see below).
After I load the project into the designer everything works perfect.

  • Open ws connection
  • LogIn as system user
  • Send '{"cmd": "experimental.structure_store.variable.list","data": {},target:"guid-of-project"}';
    experimental.structure_store.variable.list failed. code=17 msg=project not loaded

How can I start the workspace project with the WebIQ API? I had a look to "project.load" command, but without success.

I found the solution. It is the WebIQ API command "workspace.recover".

Description from docu:
Attempts to load a workspace with the given GUID. May be used if a software component was shut down before the workspace was properly closed. Workspaces are automatically garbage collected after not being accessed for 30 days.

My conclusion. Additionally to the recover of the workspace, the project is also started.

  • Open ws connection
  • LogIn as system user (command user.login)
  • Start project with command workspace.recover
  • Now project is running and I can execute other API commands
